Designed for long range measurements across your entire job site, the self-leveling LL500 features a 1,600’ (500 m) working diameter and increases productivity by reducing the need for multiple setups. The LL500 allows for easy one-person operation and features a built-in “out-of-level” shutoff that maintains accuracy over the entire work area and minimizes errors. The laser transmitter sends a laser beam to provide an elevation reference that can be picked up by the included HL700 Laserometer. The HL700 measures and displays beam location and features dual-sided LCD’s. The HL700 displays how far you are from on-grade, allowing for fast elevation checks without moving the rod clamp. A 127 mm (5”) reception height speeds beam pickup in grade match and alignment applications. The HL700’s anti-strobe sensor prevents construction lights from setting off the receiver so that true laser beam signals are more easily identified.
